    Error diagram. The following diagram shows the convergence rates of
    the method symmetric (t = -1) and the unsymmetric (t = 1) method.

    The diagram above was created using the following commands: @code
set logscale x
set logscale y
set grid
set grid mxtics
set grid mytics
set key top left
set xlabel 'h'
set ylabel 'error'
set data style linespoints
plot 'linearDG1d_t1.gnuplot' using 2:3 title 'maximal nodal error, t=1', \
  'linearDG1d_t-1.gnuplot' using 2:3 title 'maximal nodal error, t=-1' @endcode
